IMPROVEMENT IN DRAG-SAWING MACHINES.

Speeilication formirg part of Letters Patent N0. 220,443, dated October 7, 1879; application tiled May 31, 1879.

To all 'whom it may concern:

Beitknown that I,ALEXANDER A. STUcKEE,

, of' Harrisonville, in the county ot' Shelby and State of Kentucky, have invented certain new and useful mprovements in Drag-Sawing Machines; and I do hereby declare the following to' be a full, clear, and exact description ot' the invention, such as will enable others skilled'in the art to which it appertains to make and use the same, reference being had to-the accompanyin g drawings, and to letters of refer- 1 ence marked thereon, which form a part of this fully described, and particularly pointed out in the claim.

Referring to the drawings, A represents the base of the frame ot'` the 1nachine,\`vhich is either slotted at B-or made in two parts, O O. Uprights D D, rising from the base A, support a crank-axle, E,`upon one end ot which is a band-wheel, F.

The base A is provided with legs G G at its rear end, and from a' cross-piece, H, rise inclined uprights I I, which support the driving-wheel J. A belt, K, connects the drivingwheel J with the band-wheel F. Braces L L strengthen the uprights D D, and a brace, M, strengthens the uprights I I. A lever, N, having its fulcrum at O in the support P, is connected, by a pitman, Q,-\vith the crankshaft E.

A crosscut-saw, It, is connected to the lower end of the lever N,.and projects at the front end of the base A, as shown.

The lever N and pitman Q are each provided With a series of holes, whereby their fulcrums can be changed in order to regulate the length ot' the stroke ot' the saw.

A weighted guide, S, provided with anotch to receive the back of the saw It, is hinged by arms T T to the front of the base A.

A dog, U, is provided at the front of the base A, to be driven into the log while being sawed to hold the frame in place.

Staples a a are provided in the front end of the base A to receive a rod of wood, b, for the purpose ot' holding the saw in an elevated position during transportation of the machine.

Acounter-balance or weight, c, is provided at the outer end and upon the back of the saw, to give it the required direction and to hold it to its work.

Appropriate handles are provided for conveniently transporting the machine from place to place.

From the foregoing description the operation of the machine will be obvious.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a sawing-machine, the combination, with the saw and the driving mechanism, consisting of the band-wheel J, endless band or belt .K, band-wheel F, and crank-shaft E, of the intermediate connecting mechanism, consisting ofthe pitman Q and pivoted lever N, each provided with a series ot' holes, substantially as and for the purpose herein shown and described.

ln testimony that I claim the foregoing I have hereunto set my hand this 19th day of April', 1879.

ALEXANDER A. STUOKER.
